The Victron Orion-Tr Smart 24/12-20A (240W) Isolated DC-DC Charger is a compact, intelligent solution for powering a 12V electrical system on the move. It acts as an isolated DC-DC charger and a constant-voltage power supply, charging your auxiliary battery while protecting the starter battery, even with long cable runs or voltage drops from Euro 5/6 smart alternators.
-
Isolated DC-DC charger and constant-voltage power supply: Keeps your auxiliary battery charged while preventing starter-battery discharge, even on long cable runs.
-
Bluetooth Smart Enabled: Monitor, adjust settings, and update the charger from any Bluetooth-enabled device using VictronConnect.
-
Wide input range and engine-running detection: Input range 16–35 V; designed for Smart Alternators (Euro 5/6) with engine running detection to prevent starter discharge.
-
Fully programmable charging: Choose a configurable battery charge algorithm or fixed output to match your battery chemistry and usage.
-
Adaptive 3-Stage Charge Algorithm (Lead-Acid): Bulk, Absorption, Float with optimized absorption times to prevent overcharging during shallow discharges and ensure complete recharge after deep cycles.
-
Lithium charging options: For lithium batteries, either fixed absorption time (default 2 hours) or switch to fixed output as needed.
-
Remote On/Off and flexible control: Connect a two-pole remote switch or relay; control via the H (battery +) or L (battery −) terminals.
-
Paralleling capability: Unlimited units can be connected in parallel to increase total output without limits on the number of units.
-
Protection and reliability: Short-circuit protected, high-temperature protection (output current reduces at high ambient temperatures); IP43 rated when installed with downward-facing screw terminals.
-
Versatile installation: Screw terminals require no special tools; includes an input fuse (non-replaceable) for safety and reliability.
-
Flexible usage: Functions as both a DC-DC charger and a dependable constant‑voltage power supply for critical loads.
-
Designed for demanding mobile environments: Ideal for boats, RVs, caravans, and other mobile setups where maintaining battery health is essential.
-
Key specifications: Nominal output 12.2 V with an adjustable range of 10–15 V (tolerance ±0.2 V, noise 2 mV rms) and continuous 20 A output at 40°C; engine running detection and non-replaceable input fuse support reliability.
With Orion-Tr Smart 24/12-20A, you gain precise voltage regulation, robust protection, and flexible charging that keep your batteries healthy across varied conditions—all while scaling up power through parallel units as your needs grow.
